Preston boss Paul Heckingbottom could not get over his disappointment at being held by Watford in a 2-2 draw at Deepdale.
Preston missed the chance to move back into the top six when Watford scored twice in two second-half minutes to lead 2-1 before Milutin Osmajic came off the bench, in his first game back after his three-match ban, to equalise.
Heckingbottom told BBC Radio Lancashire: "You're frustrated when you don't win, but I also know we went behind to a dangerous team, as we were pushing, they were countering on us all the time, so for us to get back into the game and score that good goal was good.
"They're a bit of an enigmatic team and enigmatic players and we gave them the encouragement in that five-minute spell when they scored and they came alive, they could show off. At that point, we showed real good character to get back in the game.
"I shouldn't really feel this flat, but for some reason I do, because I know it was a good game. I enjoyed the effort and the spirit and moments and spells in the game, how well we played, but I'm just frustrated."
